| Abstract: | The paper analyzes the DDS operating principle, and a sine wave is generated by means of DSP Builder for simulating the signal source, and the realization of digital modulation methods including AM, FM ASK etc. are introduced. The results indicate that various modulation signal can switch expediently through linking modulating signal and carrying signal by multi-path selector. |
